Equipment use and status display

Alarm self-test to start with use:

When the alarm is powered on for the first time, the LCD will display “888PPM”, whilst the buzzer will sound and flash the red light, then the alarm will enter a 10-second countdown. After the countdown, the LCD will turn off. Enter the low power monitoring state.

Working state:

1. When the alarm is in the off-screen state, the green LED flashes once each 15 seconds, indicating that the alarm is in a normal state.

2. When the alarm detects CO concentration over 50PPM, the LCD screen lights up, indicating that the alarm has entered the alarm state.

3. When the alarm detects CO concentration over 300PPM, the LCD screen lights up, the red LED flashes and the alarm sounds, indicating that it has entered the alarm state.

LCD screen display instructions:

‘Err’ on the LCD to indicate the unit is malfunctioning.

‘Lb’ on the LCD to indicate it low battery and need replacement.

‘999ppm” on the LCD to indicate CO level over 999ppm.

If the CO leakage is less than 999ppm but over 30ppm, it would show its actual concentration.

Package Include:

2 x Carbon Monoxide Alarm

4 x Screws

4 x Anc
